The International Space Station, home to a continuous human presence in orbit for more than 25 years, is preparing for retirement around 2030. Over that time, low Earth orbit has served as a laboratory, home and engineering testbed. The transition is expected to shift operations toward commercial space stations now in development, raising questions about whether they can sustain humanity's uninterrupted presence in space.
